OILER FOR SPRINGS OR OTHER DEVICES TO BE LUBRICA'IED Application filed Sep tember 15, 1924. Serial No. 737,788.

My invention has relation to an improved oiler for springs, or other devices to be lubricated. g

It is, of course, a greatadvantage that the springs of a vehicle, and particularly an automobile, be frequently oiled or lubricated. It is a common practice to spread oil or kerosene over the leaves of a spring by an ordinary paint brush, relying upon the oil working its way in between the leaves constituting the spring.

Or, again, in arages, the leaves ofthe spring are spread apart by suitable implements, and oil forced into'the spaces between the leaves.

These methods not only require considerable time and eifort, but furthermore do not attain entirely satisfactory results.

The primary object of my invention is to provide an oiling device designed to be carried by the spring, and to automatically feed oil from a tank or reservoir, forming part of the device, to the under sideof the top leaf of the spring, the said oil then passing or travelling to and between the successive lower leaves of the springs, with the result that a constant supply of the lubricant'is carried between the plates or leaves, and hence the springismaintained in a thoroughly lubr-icated conditlon.

lVith the above primary object, and other incidental objects, in view, the invention con sists of the devices and parts, or the equ va- 'lents thereof, as heremafter more fully described.

In the accompanying drawing; 7 Fig. 1 is a transverse section of aseries of leaves of. an ordinary automobile spring,

showing my improved device clamped to the upper leaf or plate thereof, portions of said device being broken away; and

Fig. 2 is a plan view of the top leaf of the spring showing the oiler in connection there} with. 7

Referring to the drawing, the numeral 3 indicates the clamping rod or arm of the de vice. One end of thisrod is provided with a downwardly turned or hooked portionl, and the opposite end, forfa desired distance, is reduced, as indicated by the numeral 5, the reduction in diameter forming an annular shoulder 6. .For a short distance out- 'wardly from the shoulder 6,the reduced portion is plain o r-unthreaded, as indicatedby thenumeral 7,..whereas the;remainder of the reduced portion is'threaded;

Mounted on the plain portion ,7 is a clamping collar 8, which is adapted to be forced against the shoulder 6. A nut 9 is adapted to be screwed onto the threads of the reduced portion 5, said nut belng provided with an outer enlarged hexof an integral extension projecting from the hexagonal head of the nut,'but I prefer to make the tube separate, and provide thereon a hexagonal turning head. 16. 'The inner vend of this tube is threaded for a desired distance as indicated by the numeral 17, the said metallic washer 11, preferably or reservoir 12 is prothreads engaging interior threadsformed in I p the enlarged bore of the hexagonal head 10 of the nut 9. The bore of the tube 15 com- 1 municates, at one end, wit-lithe interior of the tank, and at its opposite endwith a lon- 'gitudin'al bore 18 formedin the reduced portion 5 of the clamping rod 8. This bore 18 in turn communicates with an oil passage or recess 19, formed in the inner face of a depending portion 20 of the clamping collar 8.

The numeral 21 indicates the several leaves of the spring, and it will be noted that the lower end of the oil passageor recess 19 terminates at a point where the oil flowing therethrough can pass between the contiguous or meeting faces of the two up- I permost plates 'orleaves of'thespring. In adjusting the device to therupper plate or leaf of the spring, the hooked portion 1 of the clamping rod is first made to engage over the curved edge'of: said upper plate, the

nut 9, of course, having first been loosened,

in order to permit the clamping collar 8 to arrange itself adjacent the opposite rounded edge of the upper plate of the spring. The

clamping collar 8 is then slid along the plain portion 7, until it abuts'against theshouldei '6. a The nut 9 is now tightened, and this will have the effect of forcing the split washer ing collar -'8.

" yl t' he outer. face of; the cla pthence into the oil passage 19 anddown-i wardly therein, to. and between the flat contactingfaces ofthe different leaves of the spring.

Erom the foregoing, it will be seen that my invention .is not onlyofa simple character, but, furthermore is one that can be most readily, adjustedrto or removed from the upper plate or leaf of the spring, and thatthe'. arrangement is such that perfect lubrication; over the entire. spring is obtained. I

Furthermore, the device is so constructed that itcan be;dismantled for cleaning and otherwpurposes. I

"What, Iclaiin. as my invention is:

1.; An oiler, for springs, comprising an oil; reservoir, an arm: extending horizontally therefrom, said arm, being arranged to pass over the topleaf of'a spring of the multiple le'afitype; saidarm being provided at one end :w'ithf a: fixed :clamping, jaw for. engagement with oneedge ofthe top leafiof the spring;- anclvbeingr further provided with an oil passage in. communication atone end with th'e'Oillreservoir, and at the opposite end in c'ommunicationvwvith a branch passageof such length'that the lower end thereof williterm-inate ata; point to cause oilto flow; between the-ineeting faces ofqthe two upper leaves l'of the spring, a. slidable cl amping' member. on' the arm. for engagement with the opposite edge of the top leaf of the spring, and'means for forcing and'freleasably retaining the collar in clamping position.

2'. An oiler. for springs, comprising an arm adaptedto be secured over the top leaf or plate of a spring of the multiple leaf type, said arm provided medially with a shoulderand-with a plain or unthreaded re-- ducedportion: next to'the shoulder, the remainder: of the reduced portion being threaded, the-said reducedportion also providedsvvith: an interior longitudinal passage extending outwardly" to the, end thereof, a clamping collar; slidable on they plain un threaded"portion;- of; the arm, and provided with a downwardly extending projection having: an oily channel 'or. passage of: such ln'g-thi that the lower' end: thereof;- Will discharge the; oil f between; the; meeting faces; of

thmtlwog upper leaves ofrthel springg gandwith which oil passage the longitudinalfoil sage of the reduced portion of the arm communicates,; a nut 0n the threaded portion of the arm and adapted to be turned so as to force the clamping collar against the shoulder of the arm, and-means for supplying a lubricant to the longitudinal oil passage of the reduced portion of the arm.

3. An oiler for springs, comprising an arm adapted to be secured over the top leaf or plate of a springof thegmultiplei leaf type, said arm provided medially with a shoulder and with a reduced portion extend mg from theshoulder, the reduced portion next to the shoulder being plain or un-.

threaded, and .theremainder of said reduced portion being threaded, and said reduced portion also providedfwith an. interior. longitudinal passage extending; outwardly to the end thereof, a clamping collarslidableon the plain unthreaded. portion or, thearm, and provided with a downwardlyextending projection having an oil channel or passage of such length that it will terminatefat' a point to cause the oil to flow between the meeting faces of the two. upper leaves of the spring, and with which oil passage the. longitudinal oil passage of the reduced portion of the arm communicates, a. hat on the threadedportion of the arm, a washer mounted on the arm between the inner end of the nut andthe clamping collar, and means for supplyinga lubricant tothelongitudinal oil passage of the arm.

4:. An oiler for springs, comprising an arm adapted to be secured over the top leaf or plate-of a spring of the multipleleaf type, said, armprovided medially .with a shoulder, and with a reduced portion extending from the shoulder, said, reduced portion next to the. shoulder for-a desired distance being plain or unthreadechand; the remainder of the reduced portion being threaded, and said reduced portion also pro vided with an interior longitudinal passage extending outwardly to the end thereof, a clamping collar slidable on the plain unt-hreaded portion offthe. arm, and provided with a downward extension having any oil channel or passagejofsuch; length that the lower end thereof will be in a positionto discharge the oil between theineeting faces ofthe two upper, leavesof the spring, and with which oil passage the longitudinal-oil passage. of the reduced portionof thearm communicates, a nut: on the reduced threaded portion of the. arm,,andiadapted tobeturned so-asto .forcethe clamping collar against the shoulder of the arm, an
